Hi Everyone - I just upgraded my home theatre soluion from a PlayStation 3 for Blu-ray/DVD playback (and maybe some games), LG 47LG70 TV and Pioneer VSX-1019AH surround receiver to an LG BD660 3D Blu-ray player and LG 55LW5700 3D TV. I kept the VSX-1019AH receiver. [To tell the truth my nine-year-old had taken over the TV room playing games...]

Here is my problem: The VSX-1019AH apparently cannot pass through 3D Blu-ray signals (e.g. I think the HDMI on the Pioneer is only 1.3, not the 1.4 required for 3D). When I try to play a 3D Blu-ray movie all I get is a blank screen (and the HDMI indicator on the receiver flashing like mad).

My first solution: Use the LW5700 TV as the "switching" device and then use the TOSLINK output to the VSX-1019 for surround sound.
Problem: Apparently the LW5700 (and it seems like most other TVs) "down mix" the audio output from surround to two-channel. Obviously, this won't work.

My second solution: Use the VSX-1019 for all inputs (e.g. set top box, old VCR) both audio and video EXCEPT the video from the Blu-ray player would go directly to the TV via HDMI and the audio would go to the receiver using TOSLINK so I would be able get surround sound.
Problem: I now have the audio and video out of sync. Not by much but enough to be annoying. I *think* that the problem is that the video signal via HDMI via the receiver has a little extra processing that slows down the signal before it gets to the TV whereas the audio signal is, well, "direct".

I have tried setting the BD660 Blu-ray player's digital output based on the manual to:

PCM Stereo - Select if you connect this unit's HDMI OUT or DIGITAL AUDIO OUT jack to a device with two-channel digital stereo decoder. No Good: I want surround sound.

PCM Multi-Ch - Select if you connect this unit's HDMI OUT jack to a device with multi-channel digital decoder. No Good: I cannot use the HDMI output.

DTS Re-Encode: Select if you connect this unit's HDMI OUT or DIGITAL AUDIO OUT jack to a device with DTS decoder. I do not THINK that this works - I seem to get the audio/video sync problem.

Primary Pass-Thru: Select if you connect this unit's DIGITAL AUDIO OUT and HDMI OUT jack to a device with LPCM, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS and DTS-HD decoder. Also I do not THINK that this works - I seem to get the audio/video sync problem.

That is what I have to do. My BD sends audio to AVR via digi CoAx, sends Video to TV via HDMI, when both audios are on, there is a slight lag. No HDMI on my AVR. However, by using my AVR for vol, and turning the TV's vol down, everything synchs up.

Not sure about your receiver but if you are having lag from audio to video there should be a setting in the receiver to correct that. For my HD Cable box i had to use a 50 mili second delay, BUT for my Blu-ray I had to use 250 mili second delay which is the highest you can choose.

nfld.republic,
I just got an LG 47LW5700 and am considering buying a 3D Blu-ray player and connecting it to my TV via HDMI. I have the TV connected to my old AVR via the TV's optical audio output. When I watch streaming Netflix movies, the TV seems to pass along a 5.1 channel Dolby Digital signal just fine (although it isn't a Dolby Digital *Plus* signal). Are you saying that the TV will not take Dolby TrueHD or Dolby Digital Plus audio that is coming in via HDMI, convert it to a regular Dolby Digital signal, and send it to an AVR via the optical audio output?
